Porn filmed in departure lounge

A porn star secretly bared all of her assets in a movie shot secretly at Hong Kong's airport, with backdrops including a departure lounge.

Red-faced officials from the airport authority officials have now stepped up security to make sure Chek Lap Kok airport doesn't appear in any sequels to the hour-long film, titled Exposure Trip in Hong Kong.

The film was reportedly produced by a Japanese company.

"We were not aware of the unauthorised filming. Otherwise we'd have stopped it," airport authority spokeswoman Sylvia Chan said today.

The Sun newspaper earlier reported that about 20 minutes of the video were filmed in and around the airport, and copies were available in pirate stores in Hong Kong.

Chan said the airport authority prohibited any activities that harmed the airport's image.

Officials have made a complaint to police and stepped up security patrols, he said.

Airport officials were talking to their lawyers about further action, although they had been unable to identify the filmmakers, Chan said.
